ERROR 500 - INTERNAL SERVER ERROR

Hello
I have been getting this error on my wordpress site and can not access it. I have been on the phone with hostgator for days now; but they do not offer support for multisite. but what they did tell me is that on their end they are getting this error "premature end of script headers ; index.php" any idea how I can fix this

This error could be caused by many things, I would suggest checking folder and file permissions and try changing them to 705 or 755.
Check your .htaccess file and try using default rules for your type of installation, you can find them here:https://codex.wordpress.org/htaccess

If that doesn't work, try renaming your /wp-content/plugins/ and /wp-content/themes/YOUR_ACTIVE_THEME/ folder to disable plugins and switch to default WP theme and see if any of those are causing it.
